I was raised in a part of North Nazimabad, Karachi called 'Taimurya'--after 'Taimur Lang' or 'Timerlane'.
Indeed, Taimur is a hero to Pakistanis--enough to name neighborhoods to him even in the most secular country of Pakistan. And that has to do everything with contra-distinction with Indians/Hindus. Those are facts. Human facts. Nothing to do with being Muslism or Hindus or Martians.
Indians--especially Hindu Indians--have to hate Taimur. Pakistanis are not fan of 'Chengez Khan' because his off-springs sacked Baghdad (though some people still have 'Chengez' as the name--and there are plenty of 'Khans'--the most 'Khan' country in the world!)
Indeed, the Hindus in historic India were a subjugated people for centuries. That Pakistanis take pride in that subjugation has to do with the very basic of the reason for the foundation of Pakistan; but that is a psychology of fear. It is for the Indians to reach out and be the large hearted big brother. Then Timerlane or Mehmud Ghazni would be just historic figures. Not much different from, even, the Hindu protoganists from eons ago: Powerful men who went on a rampage on shady grounds.
